python3 decorator template thread decorator, timing decorator

About decorators:

    In terms of function, similar to filters and interceptors, add some custom logic before and after the execution of the original function.

    In terms of implementation, the original function is passed in the decorator parameters, and the decorator controls the execution of the original function. 

    In terms of usage, add the @ decorator function name to the original function header like a java annotation.

 

 

Decorator writing:

(1) Thread Mode_Change: It is a three-layer structure in which the decorator contains additional input parameters; when using it, there must be (), @thread mode_改()

(2) Thread mode: the decorator does not require additional input parameters, two-layer structure; there is no () when used, @thread mode

Example:

@线程模式
@打点计时
def a1(s = None):
    for i in range(5):
        time.sleep(1)
        print_加锁(s)

for i in range(10):
    a1(i)
